Against all odds, Avery has survived nearly a year of secrets, schemes, and love lost and found at Hawthorne House. She's weeks away from fulfilling the terms of Tobias Hawthorne's will and inheriting his billions.

ONE MORE PLAYER.
Avery thinks she knows all the family secrets, but when a familiar face arrives with shocking news and a plea for help, it's clear there is one last puzzle to solve.

ONE FINAL TWIST.
Soon, Avery and the Hawthorne brothers are drawn into a last deadly game against an unknown and powerful opponent. Hearts and lives are at stake - and there is nothing more Hawthorne than winning.
